Specific Character and Synonym. 
Epimepium diphyllum ; petiolis filiformibus dichotomis ra- 
- cemum unilateralem gerentibus, geniculis tumidis pi- 
losis, foliolo solitario in utroque ramo, petalis planis. 
Erimepium diphyllum. Lodd. Bot. Cab. 1858. 
The petals (nectaries, Linn.) of this rare plant possess a 
form extremely unlike that which occurs in Ermepium al- 
pinum, but the variation is precisely similar to that which 
exists occasionally in Aguiteeia, and cannot form a generic 
distinction, where the whole habit of the plant, and the 
structure of every part of fructification, except the corolla, 
is precisely as in the common species. I have taken a dif- 
ferent view of the petiole, and the origin of the flowers, 
from that which is commonly received, but it seems to me 
simplest, and that which best explains the appearances, 
This species is a native of Japan. We received a plant at 
Edinburgh from Berlin in 1834. It flowered pretty freely 
in the greenhouse of the Botanic Garden early in spring. 
I do not find the hairiness of the petiole, excepting at the 
joints, nearly so great as is represented in the Botanical 
Cabinet.
